A cutting member for a saw chain and a method for the production thereof, the cutting member comprising a support part made of a steel alloy and a cutting part welded to the support part along a welding connection made of a high speed steel. The steel alloy of the support part is a tool steel that has the following composition (specifications in % by weight): Carbon (C) 0.4 to 1.0 Silicon (Si) up to 1.8 Manganese (Mn) up to 0.6 Chromium (Cr) 4.5 to 12 Molybdenum (Mo) up to 3 Vanadium (V) up to 2 Iron (Fe) and accompany elements caused by melting and impurities as the remainder. The steel alloy of the support part in a quenched and tempered state has a hardness of more than 600 HV and a tensile strength of more than 2000 MPa as a result of curing at a suitable temperature above the austenitizing temperature of the high speed steel.
A cutting member for a saw chain, the cutting member consisting of a compound material consisting of a support part, a cutting part, and a welded seam connecting the support part and the cutting part,
